【Abstract】 The design procedures of the feed water automatic regulating system for the 200MW unit in Zhengzhou Thermal Power Plant are presented. Some successful design skills about the system functions are described, which include the measures improving system regulating behaviours, the undisturbed change-over between different regulating schemes, the improvements of accuracy and reliability of water level signal measuring and the coexistence of both soft and hard monitoring funtions.更多还原
